NAME-PLATE ATTACHMENT.

Specification of Letters Patent. Patented Sept. 13, 1921.

Application filed July 5, 1921. Serial No. 482,461.

To It whom it may comment.

lie it known that I, ()nor NnLsoN, a citizen of the United States,residing at Attleboro, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inName-Plate Attachments, of which the following is a specification.

. My invention isan im roved means for connecting a name or em lem plateor the like to any desired supporting surface. Theimmediate andparticular object 1 have in view is to secure a name or emblem plateupon the shell or cover of theradiator of an automobile. This radiatorshell is in effect a cover for the radiator proper. which is a cellularor tubular element, through which the heated water fromthe water jackets of the motor cylinders is passed to dissipate heat units to theair, and the shell fits the radiator closely, so that it is diliicult orimpossible to insert hands or tools between the shell and the radiatoror to get at the inner surfaces of the shell without removing the shellfrom the radiator.

In the drawings:

Figure 1 is a central section of the upper part of an automobileradiator, showing the shell covering the same, with a name plateattached Fig; 2 is a rear view of a name plate, with its attachingdevice;

Fig. 3 is a perspective view of the attaching device;

Fig. 4 is a section on line 4-4. of Fig. 2;

Fig. 5 is a section on line 5-5 of Fig. 2;

Fig. 6 is a plan or front view of the plate or shell member, withaperture formed therein;

Fig. 7 is the same, after pressing the bridges back;

Fig. 8 is a cross-section on line 8-8 of Fig. 7

Fig. 9 is a rear view of the name plate, attached Fig. 10 is a sectionon line 1()1() of Fi 9;

ig. 11 is a cross-section on line 11-1l of Fig. 7

Fig. 12 is a cross-section on line 12-12 of Fig. 9;

My connector is made in two parts and the engagementbetwcen the twoparts is a positive locking engagement, and is not merely a frictionalei'igagement. The engagement and locking is accomplished by theintcriwtion oil the parts themselves, when they are brought together.The result is that the engagement is elfected with the utmost simplicityand is positive, so that the vibration of the machine, in use, has noeffect whatever upon the union of the parts, which retain theirengagement until force dcsignedly applied between the parts in thedirection of the longitudinal axis of the automobile, to separate them.

In the preferred form of my device, I no vide a tang member, which .isshown in fig. 3. The member is struck up from a blank, to bend; the fourarms, as shown inFig. 3. The short arms a, which are preferably shapedto a curved outline at their free ends. are bent: to a right angle withthe central portion of the blank. The long arms l) are bent to an angleof less than 90 with the central portion of the blank, preferably to anangle of about The central portion 0, is then secured by soldering orotherwise, to the back of the name or emblem plate (if, which is to beattached or connected.

In another plate. or preferably in the substance of the front of theradiator shell 6, at the desired point, I 'form three apertures f and g,substantially as shown in Fig. (3. The metal within the dotted lines,Fig. 6. is then depressed slightly, leaving the surtaces within thedotted lines slightly lower than the surrounding surfaces (see Figs. 7,8 and 11). The central square aperture f, is of a size to receive theshort tangs (I, along and against its upper and lower edges, the widthof these short tangs being equal to the width of the upper and lowersides of the square aperture. The ends of the short tangs are preferablycurved, so that in applying the name plate, these short tangs enter thelarge aperture and serve a pre liminary purpose in centering andpositioning the tangs and plate. The ends of the long tangs b, whichstand at an angle to the back of the plate, less than 90 as shown inFig. 5, encounter the depressed surfaces or bridges 7i, and, as pressureis applied to the name plate, the ends of the long tangs spread apart,and pass into the narrow slots g, and as pressure is continued the tangsbend more and more back to their original position relative to thecentral portion of the tangmember, as shown in Fig. 12, that is. theyare flattened out, with their free ends extending through the slots 9,along the inner side of the plate (Z, in which the slots are formed. InFigs. 13 and let, I show a tang member having four tangs and a platemember having four narrow slots to receive the four tangs as they arebent in the process of forcing the name plate, with its counectetjl tangmember, to a locking engagement. This embodiment of my invention is notin substance different from the preferred form in. the means and methodof locking the parts together. It lacks, however, the guiding andcentering action which is present in the preferred form due to theaction of the short tangs a, perpendicular to the surface of the back ofthe name plate. A further reason for preferring the constructiondescribed above as preferred, is that more force is required to bend andinterlock four locking tangs than is required for two, assuming thesheet metal is of the same gage in both cases. As the two locking tangs,plus the short tangs,.give a perfectly secure connection and provideagainstany movement of the plate, longitudinal, lateral, vertical'orrotative, and require less force in application, they are naturally tobe preferred even if the preferred form had no other advantage.

The metal employed lor the tang members is flexible, but practicallynon-resilient.

I claim:

1. The attaching device above described. consisting" of a pair of tangs.their free ends spreading from a common center in opposite directions,and a second pair or tangs perpendicular to the back of the plate to beattached, both pairs of tan rs being secured upon the back ol the plateto be attached; a socket mcmher having al'icrturcs to receive the saidtaugs and surfaces againstwhich the spreading ends of the one pair oftang-s impinge. in application. to spread said tunes into loclcingposition. and guide them to the tang receivii'ig apertures.

12. The attaching dcvice above described, consisting of a pair of(Bangs. their free ends spreading from a common center. in oppositedirections, and a second pair of times perpendicnlar to the back of theplate to be attached, both pairs of taugs being, secured upon the backof the plate to be attached.
